Mr Leech tweeted the picture to Lidl with the caption: ‘Hi LidlUK, I wonder if you could let me know how this mouse got into my packet of rice. Now my house stinks of cooked mouse and my wife is uncontrollable vomiting.’

A member of the supermarket’s team responded to Mr Leech and said: ‘Hi Rich, sorry to see this. If you pop us a DM with your contact details, we’ll get this looked into for you.’

It is unclear how the mouse managed to get into the packet of rice.

A spokesperson for Lidl has since told Metro.co.uk: ‘We were very sorry to see this and have requested further information from the customer, so that this can be fully investigated by our quality assurance team.’
